Subclass for random search tuning.
The random points are sampled by paradox::generate_design_random().
In order to support general termination criteria and parallelization,
we evaluate points in a batch-fashion of size batch_size.
Larger batches mean we can parallelize more, smaller batches imply a more fine-grained checking
of termination criteria.
R6::R6Class object inheriting from Tuner.
TunerRandomSearch$new(batch_size = 1L)
tnr("random_search")
